Final answer:
In New Hampshire waters, when approaching a spar buoy that is white with a black top, boaters should keep the buoy on their starboard (right) side when moving in the upstream direction to ensure safe navigation.
Step-by-step explanation:
When approaching a spar buoy that is white with a black top on New Hampshire waters, it is important to know that such buoys are generally used as navigational aids, and the colors signify certain actions for boaters. In the United States, a spar buoy that is white with a black top typically indicates that boaters should keep the buoy on their starboard (right) side when proceeding in the upstream (returning from sea) direction. Therefore, to ensure safe navigation and compliance with maritime regulations, boaters should maneuver their vessel to pass the buoy while keeping it on their right-hand side.
When approaching a spar buoy that is white with a black top on New Hampshire waters, you should keep a safe distance from the buoy to avoid any potential hazards. Spar buoys typically mark the outer limits of a channel or indicate a turn or bend in the waterway. In this case, the white color indicates that the buoy is starboard or right-hand side of the channel, and the black top helps with visibility.
